To all whom it may concern:

Be it known that I, PIERRE BARNEs, a citizen of the United States,residing at Seattle, in the county of King and State of Washington, haveinvented certain new and useful Improvements in Water-Heaters orSteam-Generators, of which the following is a specification.

This invention relates to thatclass of heaters which are designed to beutlllzed fol warming the apartments of a building by the circulation ofa body of water or steam,

' through a system of pipes and radiators and its object is to improvethe construction of heaters and parts thereof constructed su'chheaterstoprovide one having exceptional eificiency.

. The invention consists in the novel con-' struction and combination ofparts, as will be'hereinafter described and claimed.

1 The accompanying drawings illustrate in accordance with 'my invention.

Figure 1 is a vertical cross sectional view of an embodiment of theinvention; and Fig. 2 is a horizontal section of one of the heatingmembers thereof.

The'reference numerals 10 designate the main, or circulating,water-heating members. These members are each comprised of and acentrally disposed boss, or hub, 12 co'mmunicatively connected therewithfrom diamet of the respective circular portions. Intermediate theboss-openings of each such memhers is a partition 17 arrangedto affordan ;indepeudent communication through the arm'lh between the opening 15and the circular chamber upon the one side and a like connection throughthe arm 14 between the other opening 16 andthe chamber from the. otherside. Thes members may be employed alternately with ancillary heating"members 18. The-members 1b severally coneist of a lenticular shell ofless diameter than that of said circulating members and having acentrally disposed outlet opening 19 at the top, and an inlet opening 20below, the latter being located centrally or otherwise according to thelocation of the member in the series to conveniently accommodate thewater-supply pipe 21 which enters the lowermost member. Said members arecommunicatively connected by tubular fitopenings.

tings 22 which are socketed in the respective Where the heater isconstructed to be used for the generating of steam, a blow-oft pipe 23would desirably be connected with the lower member, and a down-flow pipe24; would be utilized to make communication between the upper and lowercompartments of the correspondingly disposed members by being extendedthrough apertures provided in the intervening partitions 17. Thisdownfiow pipe is of less diameter than the tubular fittings 22 betweenthe several members to afford annular passages 25 for the upflow of thewater between the adjacent heating members. The upper of said members isad- .vantageously made of greater diameter and depth than thecirculating members therebelow to furnish an extended water surface tofacilitate the disassociation of the steam from the water and also toprovide ample storage capacity for the liberated steam.

27- represents a pipe connected with the top member of a series for theoutflow of hot water or steam, as the case maybe.

The furnaces 28 and casings 29 for the heaters may be made in variousways and require no special description. The illustration shows afurnace adapted for burning fuel, such as coal or wood, and'isprovidedwith a grate, denoted by 30.

1 The operation of the heaters may be explained as follows: a suitablefire being'had within the furnace will act most directly upon the lowerheating-member of a group 7 and thence the flames and other hot combustion products pass upwardly through the spaces of the circulatingmembers 10 and will, after parting with a large proportion of its heat,escape through the smoke outlet The ancillary heating mcmbers 18 serveas battles to cause the hot gases to be directed to effectively subjectthe exposed sur faces of the heating members 10 to the action of theheating agent. The members being thus affected will heat the watercausing it have a movement upwardly from the lowest to the highestheating-members, passing freely through they ancillary ones, butretarded in the flow through the circulating members. The manner. inwhich the water is directed in itspassage throughthe said Icircu'letingmembers will be understood .lower members by the downfiow pipe from aninspection of Fig. 52 wherein represented by darts the current courses.l ore particularly, the water enters the in s of such a member frombelow and diverted by the partition 17 to first fiow radially out wordthrough the hollow arm 13 into the annular chamber 11 wherein the bodyoi. Water is caused to flow in two semicircular branches to thediinnetriczilly opposite side of the member whereat it reunites andflows {is a single stream through the other arm 143% to the cavity inthe boss which is above the partition, whence it flows from thememl'ier. In the adaptation of the devices to the uses of a steamheater, the circulation of the ter is established between said upper andwhich being more remote from the direct uction of the heating agent thenthe sin-rounding fillings 20, thus causing a difference in thetemperatures of water within the pipe from that outside with itcorresponding;- ditfercnce between the specific gravities and thusinsure a descent of the waterwithin the pipe While the water feturnsupwardly within the successive members and their connecting tubularfittings. It *ill be observed that said down-flow pipe opens on theopposite side of the partition 17 in the boss of the highcstmembcl" 10from that to which the Water circulating upwardly from the lower membersis delivered. struction, the water which enters suid high est member iscompelled to circulate through one of the two oppositely extending arms,through the circular shell and through the other arm before it can passdown through the pipe 25. This circulation of the water insures aperfect separation of the steam from the water and thereby gives thell'itttdl' a maximum capacity for generating steam. The pipe 27, whichcarries oil the steam communicates with the boss of the highest memberat the side of the partition on which o the pipe 25 opens in order tofurther insure the complete separation of the steam from the Water.

What I claim, 1s-

1. A heater com risin e series-of sneer-- posed water-holding membershaving trally arranged connections for the upliow of Water between thesuccessive members, tlle upper of said members being arranged to afforda horizontalcirculation of water therein, and a connection disposedaxially of the aforesaid connections and making an in dependentcommunication between the upper and lower members, so as to cite ct there turn of the water to the latter after a circulotion thereof hasensued in said upper member.

2. in e Water l1 ster of the chi" scribed, the combination, with Msuperpos horizontal wean;

tion t Because of this conmembers, of it plurality of Watenholding' ersavenged alternately of said circumembers, each of said circulating comprs up; a. continuous outer shell, a. co trelly disposed boss, and

two oppositely extending arms connecting said boss and shell, each bosshaving a. partilverein with e passage at one side therele rdin from itslower end to one of said at and a passage its other side leading i ron'iits upper end to the other arm,

axialiydisposed tubule-r connections ,be-

tween said water-holding members and the in. s o said circulatingmembers, said s runs superposed members terminating at the bottom with aWater-holding member and at the top with a circulating member, a
